摘要:
A head suspension assembly for use in a disk drive having a load and unload ramp, the head suspension assembly including a load beam, a cover having a load and unload tang, a coating sandwiched between the cover and the load beam, and a head lead wire extending through the coating. In a preferred embodiment, the coating is a visco-elastic thermoplastic adhesive and the cover is a constraining material; whereby the cover is adhered to the load beam and undesired vibrations of the head suspension assembly are dampened. In a method of fabricating the head suspension assembly, the cover is placed over the load beam after the coating is applied and after the head lead wire is strung over the load beam, and then the cover is adhered to the load beam by heating the coating, preferably by placing a heated platen over the cover. Consequently, the load and unload tang, which is part of the cover, is not an obstacle when routing the head lead wire over the load beam and bonding the wire to a slider, and the head suspension assembly fabrication process can be automated.
